A

Systolic anterior motion of the mitral valve leading to anterior motion of mitral valve leaflets toward interventricular septum. Contact berween mitral valve and thickened septum during systole leads to LVOT obstruction.

Q

What is the best method to detect ischemia in a patient who cannot exercise?

A

Dipyridamole or adenosine in combination with thallium or sestamibi. 2. Dobutamine in combo with echo

22
Q

What is the next step after determining someone has reversible ischemia? in someone who has chest pain and is stable?

A

Cornary angiography which is the most accurate method of detecting CAD. Exercise tolerance test

23
Q

When is CABG indicated?

A

3 vessel disease with atleast 70% occlusion, left main or 2 vessel disease in diabetics

24
Q

What medications lower mortality in chronic angina?

A

Aspirin, beta blockers, nitroglycerin (oral, transdermal)

25
Q

What meds are used in ACS when patients arrive in the ED? Which ones are best used to prevent restenosis?

A

Aspirin + clopidogrel, prasugrel or ticagrelor (P2Y12 inhibitors on platelet). Prasugrel or ticagrelor

26
Q

When is clopidogrel used?

A

In combination with aspirin on all acute ACS. Aspirin intolerance. Recent angioplasty with stenting.

27
Q

What is a risk of using Prasugrel?

A

Dangerous in patients 75 and older because of risk of hemorrhagic stroke.

28
Q

When is Ticlpidine used and what is its side effects? What do you use in angina refractory ot persistent through other treatment?

A

IN patients intolerant of both aspirin and clopidogrel. Causes neutropenia and TTP. Ranolazine.

29
Q

When do you use ACEi/ARBs in CAD?

A

Low EF/systolic dysfunction (best mortality benefit). Regurgitant valvular disease.

30
Q

How does hydralizine work and why is it used?

A

Direct acting arterial vasodilator. Decreases afterload and has a clear mortality benefit in patients with systolic dysfunction.

31
Q

What is the LDL goal in patients with CAD?

A

Less than 100 mg/dL

32
Q

What are CAD equivalents?

A

PAD, Carotid disease, Aortic disease, Stroke, DM

33
Q

What is the most common effect of statins?

A

Elevated AST and ALT

34
Q

Which hyperlipedemia drugs are associated with a clear mortality benefit? What effects does it have on coronary arteries?

A

Statins. Antioxidant effect on endothelial lining of coronary arteries

35
Q

What is an adverse effect of fibric acid derivatives? cholestyramine?

A

Increased risk of myositis when combined with statins. Flatus and abdominal cramping.

36
Q

When do you use CCBs in CAD?

A
  1. Severe asthma precluding the use of betablockers
  2. Printzmetal variant angina
  3. Cocaine induced chest pain
  4. Inability to control pain with maximum medical therapy
37
Q

What is the lifetime of internal mammary artery grafts? saphenous vein grafts?

A

10 years. 5 years.

38
Q

Which conditions is angioplasty (PCI) best suited for?

A

Acute coronary syndrome, particularly with ST elevations

39
Q

What murmur is acute coronary syndrome associated with?

A

S4 gallop which is the sound of atrial systole as blood is ejected from the atrium into a stiff ventricle.

40
Q

What are the EKG findings in anterior vs inferior wall MI? Which one has the worst prognosis?

A

IWMI - ST elevation in II, III and AVF. AWMI - ST elevation in V2-V4. AWMI

41
Q

What is the First step and second step in treating a patient with ACS?

A

Aspirin, Angioplasty before pain control. Betablockers can be given any time during the hospital stay.

42
Q

When can you detect CK-MB and Troponin abnormalities? How long do they last?

A

Within 4-6 hours. CK-MB (1-2days) and Troponin (10-14 days). Renal insufficiency can give FP results for Troponin

43
Q

What is the most common cause of death after an MI in the first several days?

A

Ventricular arrhythmia (ventricular tachycardia, ventricular fibrillation)

44
Q

How is angioplasty superior to thrombolytics? What is the door to balloon time in PCI? Door to thrombolytic time?

A

Survival and mortality benefit, fewer hemorrhagic complications, likelihood of developing complications of MI. 90 minutes. 30 minutes upto 12 hours.

45
Q

What are complications of PCI?

A

Rupture of coronary artery, restenosis of vessel after angioplasty, hematoma at site of entry into teh artery

46
Q

What are absolute contraindications to thrombolytics? How long does the mortality benefit of thromoblytics last? When are thrombolytics only beneficial?

A

Major bleeding into the bowel (melena) or brain, recent surgery, severe THN (above 180/110), non hemorrhagic stroke within the last 6 months. Extends out to 12 hours after onset of chest pain. STEMI only

47
Q

When is Heparin first line treatment?

A

Initial therapy with ST depression and other NON-ST elevation events as it prevents clot formation that closes off the coronary artery.

48
Q

When are GPIIb/IIIa inhibitors indicated? Which patients do they give mortality benefit?

A

Abciximab, Tirofiban and eptifibatide are used in ACS patients who undergo stenting and angioplasty. Mortality benefit in those with ST depression

49
Q

When are antiplatelet drugs indicated in cardiac events? What other drugs do both conidtions get?

A

In STEMI and NSTEMI/unstable angina. Aspirin, beta blockers, statins, ACEi, morphine, nitrates.

50
Q

When do you do Post-MI stress test?

A

Identify those with residual ischemia prior to leaving the hospital
